This invention relates to liquid dispensing apparatusf Y 'One objectoi'the-invention is to-provide "simple,reliable andeificient means forautomatically draining the measuring container when the casing door ofthe apparatus is closed, as for example, when the'use' of the apparatusis discontinued for the night.

Another object is to provide a draining arrangement for liquiddispensingapparatus meetall requirements. r I I Theseand other objects areaccomplished by means ofthe arrangementdisclosed on the accompanyingsheet 'of' drawings in which Fig. 1 is a -vertical longitudinalsectional in "which the parts cooperatein a manner to View of liquiddispensing apparatus, embodying my invention; and

Fig. 2 isan enlarged detail sectional view of apart of the apparatus anddisclosing the invention.

Fig. '3' is an enlarged "fragmentary sec- Y tional'elevation through thedrain control valve. The various novel features of the invention will beapparent from the following I 7 device thus far described, it will beap'pre description and drawings 1 and will be particularlypointed out inthe appended claims.

Referring to the figures of the drawings it will be notedlthat theinvention is illustrated in connection with liquid dispensing apparatusincluding transparent measur ing s container '10 mounted betweenaibaseplate.

Mounted within the base14 is a pump 15 for pumping liquids, such as gasoline, from anysuitablesource represented by reference character 16 up through a supply pipe 17which terminates in the U-shaped portion 18 within the container 10.

An overflow pipe '19 extending up into the container 10 determines themaximum height of the liquid within said container! A verticallyadjustable discharge conduit 20 also extends into the measuringcontainer10 and below the latter is provided withan oper-v ating handle 21whereby the discharge conduit 20 may be, raised, lowered and rotated.

The discharge conduit may locked in vato hereinafter.

The drainpipe- 23 is connected at 3O to the'overflow pipe l9 so that liquiddrained from the measuring container passes "through the'drain pipe23and then through the overflow pipe 19 back to the source of "supply.Normally draining action is prevented'byf a valve 31 having-a stem 32.As",

shown in Fig. 1, the valve stenr 32 extendsout of the valve casing andthe valve, under the pressure of the usual spring, is .releasably held"W v .ther description ofsame' willnot be givenf ia in closed position.As shown in Figure 2, the valve stem is pressed inwardly by a trigger 33for opening the valve with the result that the measuring container isdrained. Referring more specifically to the valve shown in Figure 3,1twillbe seen that the valve 31 is connected to the parts oi the drainpipe 23 and is provided with the valve stem 32 operated by one arm ot'the trigger 33, the trigger belng 'pivotallysupportedas at 51 tothe'bracket 52 provided on the valve 31; The valve stem is provided withthe valve disc 53 seated on the valve seat 5a and spring pressedby'spring 55 to maintain the valve disc in normally seated position,preventing draining through the pipe S'ecured to the outer end 56 ofvthe trigger at the point 34- is a valve operating member 35, the upperend of which is provided with a lip 36 which as shown in Fig. 2 isengaged and raised by. a flange 37 on the low-er edge of the door 38 orthe casing 13.

In other Words, when the door 38 is raised for completely enclosing thecontrol mechanism of the pump, the lower flange 37 of the door 38 passesinto engagement with the lip 36 of the operating member 35v and raisesthelatter, for opening the drain valve, whereupon liquid is permittedtodrain from the measuring container 10. \Vhen however, the door 38 islowered, the valve automatically and immediately closesthrough action ofthe spring 55, the upper end ot the valve operating member 35 beingenclosed or encased by a pocket portion 39 formed at the upper end ofthe door. This pocket prevents meddling with said member and alsoimproper oper-v ation of said valve when the door is open.

thus housing the upper portion of the valve operating member .35,protective means is provided whereby the purchaser of liquid is more aptto secure the full amount of liquid purchased; i
